ActiveMechanical vibration—Rotor balancing—Part 11: Procedures and tolerances for rotors with rigid behaviour
机械振动 转子平衡 第11部分：刚性转子的平衡方法和允差
Application Summary AI generated
This standard specifies the balancing procedures and permissible residual unbalance tolerances for rotors that exhibit rigid behavior during operation. It is applied in the design, manufacturing, and maintenance of rotating machinery such as fans, pumps, electric motors, and turbines to ensure vibration levels remain within acceptable limits. The standard is used by engineers and quality control personnel in industries like automotive, aerospace, and general mechanical engineering for both shop balancing and field balancing of rigid rotors.
